Description of problem:

Listing packages (systems->system->software->packages->list):

If the client has multiple instances of a package installed for different
architectures (e.g. i386 & x86_64), the package is only listed once.  

Observation: Although there are multiple versions of the package installed on
the client, the rhnServerPackage only has a single record. 

From initial analysis, impact to backend is anticipated.

Version-Release number of selected component (if applicable):

How reproducible:
Always

Steps to Reproduce:
1. select Systems
2. select an x86_64 system
3. select Software -> Packages -> List
4. check the package list for a package that you know is installed on the client
for multiple architectures (e.g. libjpeg i386 & x86_64).  (Note: you may have to
manually install the 2 packages from the client, to observe this.)

Actual results:
Only 1 package is listed (w/o architecture)

Expected results:
Both packages should be listed and displaying the correct package architecture
in the package list.
